Application filed January 3, 1889. Serial No. 295,368. No model.)

To aZZ whom, it may concern:

Be itknown that we, PHINEAS il. ADAMS, Jr., and ORSEMAS T. X. ADAMS,citizens of the United States, residing at Chicago, Illinois, haveinvented certain new and useful Improvements in Apparatus for use inDecomposing Metallic Salts and Desulphurizing Orcs, of which thefollowing' is a specilication.

The object of our invention is to improve an apparatus for mechanicallydecomposing chemical compounds, metallic salts, and desulphu rizing oresor their resulting material, when the substances treated are in a moltencondition, b v the action of centrifugal force; and our inventionconsists in the features and details ot' construction hereinafterdescribed and claimed. i v

In the drawings, Figure l is a vert-ical lon- `gitudiual section of ourapparat-us with the running-gear in elevation. Fig'. 2 is a transverse,vertical section taken in the line 2 2 of Fig. l, showing* thearrangement of the actuating-shaft and the means employed to preventfriction, looking in the direction of the arrow. Fig, tl is a planviewof the bottom or end ot' the receivingwessel. Fig'. 4 is anelevation showingl the entranoepipe, lookingI ont trom the interior ofthe receiving-vessel; and YFig'. shows the receiving-vessel somewhatmodified in form.

ln making' our improved apparat ns for decomposing.;l chemicalcompounds, met allie salts or salts ot' metal, anddesulphnrizing'ores,wc make a vessel, Y, constructed and adapted loreceive the substance to be treated when in a molten condition. Thisreceiving-vesselmay be made in such a way as will secure the requiredstrength and reduce the conduction of heat from the interior to theexterior. It may be surrounded by curbingand have a removable bottom orend to facilitate the removal of the material which is not thrown oil atthe month by the action ot centrifugal force; and in other respects itmay be made as will be calculated to subserve the end in view and permitot its being;` rotated at a high rate oi speed for the separation ofparticles of different degrees of density in the matter treated. Many ofthese parts and the details of their construction, as they do not formthe special Subj ect-matter of our present claims, need notbe more fullydescribed, as they will be sufficiently understood from an inspection ofthe drawings. The receivingwessel, however, is intended to be rotated'ina horizontal instead of a vertical position, and therefore necessitatesa special adaptation of various parts to this end, as hereinafterdescribed.

An actuating-shaft, A, is arranged 'in horizontal journals or bearingssupported in a suitable frame-work, which may be indicated by the letterB. This frame work will of course be of a size and strength adequate tosustain the heavy weight of the receivingvessel with its load of moltenmaterial. One of the journals, C, may be a plain bearing or box, inwhich the outer end ot the actuatingshaft rests and revolves. The otherbearing,

D, however, we prefer to make as shown in Fig. 2, where it consistsfof abox adapted to receive a number of rollers or wheels, E, preferablyjournaled in suitable bca-rings in the sides of the box and affording'just snl'iicient space in the center t'or the passage of the actuatingshaft, so that its surface will bear against the surface of the wheelsor rollers E. ily this arrangement cxtreme or in jui-ionsfriction willbe prevented between the actuating-shaft an d t-he bearings as itoperates under the heavyY load or strain to which it will be subjected,as hereinafter described.

The pulleyv or belt surface F is connected to any convenient source ofpower, so as to rotate the actuating-shaft and the receivingvessel towhich itis attached. The inner end of the actuating-shaft is providedwith a collar, G, which has tlanges Il. (Shown in section in Fig. l.)This collar, with its iianges, is keyed or otherwise iixed to theactuatingshaft, so that it will rotate as it revolves. The flanges H areconnected to the bottom or end ot the reeeiving-vessel in such a way asto carry the receiving-vessel around wit-h their revolutions. XVepret'er to form this connection in a way that will permit someyieldability or iexibilitv between the parts, and

IOO

the parts apart from each other to the extent allowed by the bolts. Atthe same time the presence of thesesprings will permit sufficient playto accommodate any vibration that might occur in the receiving-vesselwhile being rotated at a high rate ot' speed, and at the same timepermit'the actuating-shaft to be rigidly held in a horizontal positionwithout being sensibly affected by the vibrations of thereceiving-vessel.

NVe have thus described and illustrated a manner of attaching` thereceiving-vessel to the actuating-shaft to permit of sufficientflexibility to accommodate the parts to the vibrations ot' thereceiving-vessel in operation; but as other means can obviously be usedto secure a flexible or yieldable connection, we do not desire tounnecessarily limit ourselves to details of construction in thisparticular.

The receiving-vessel, as before said, is intended to be arranged i`n ahorizontal position. Its mouth is made sufficiently open to permit aconstant inflow of molten material to be treated, while at the same timeit serves for the discharge of the material which is thrown off by theaction of centrifugal force. To permit this we prefer to introduce themolten material through a pipe or spout, J, which enters the mouth ofthe receiving-vessel at a slightly-downward inclination and carries thematerial to be treated almost to the bottom or farther end of thevessel. This pipe or spout leaves sufficient space around it to per mitthe passage of the molten material thrown off by the action ofcentrifugal force; and to retain the heat in the receiving-vessel Weprefer to arrange a plate or cover, X, before its mouth, provided with asuitable hole for the admission of the pipe or spout. This cover may bemade adjustable toward and from the mouth of the receiving-vessel, itdesired, to regulate the space between them. To catch the material as itis thrown oft we prefer to arrange a chamber, K, into which the mouth ofthe receiving-vessel opens. This chamber is surrounded by a curbing orother means to catch the molten material as it isthrown olf, and meansmay be employed, as a pipe, L, to discharge streams or jets of Wateronto such material in order to prevent overheating. A

Aspout is arranged at the bottom of this chamber, through which themolten material thrown olf may pass to a car, H, or other receptacleadapted to receive and remove it. To heat the interior of thereceiving-vessel,

or to prevent it from cooling during an interruption of its operation,orV for other purpose, we also prefer to provide a furnace, N, by meansof which` a blast of air, driven by a blast-fan or other means, may beheated and discharged into the receiving-vessel, as shown in Fig. l.

In Fig. 5 we have shown the receiving-vessel as enlarged and separableat the mouthy end, instead of at the otherend, as shown in Fig. l. Thismodification is for the purpose of facilitating the removal of thatportion of the material treated which is not thrown ofi by the action ofcentrifugal force, if it be preferred to remove at that instead of atthe other end of the receiving-vessel.

What we regard as new, and desire to secure by Letters Patent, is-

l. In an apparatus for decomposing metallic salts or salts of metals anddesulphurizing ores when in a molten state, the combination of ahorizontal revoluble receiving-vessel adapted to receive molten materialto be treat ed, a horizontal revoluble actuating-shaft rotating saidvessel as it revolves, a pipe or spout entering the receiving vesselthrough its mouth and discharging the molten material to be treated intothe receiving-vessel at or near its farther end, means for supplyingheat to the interior of the receiving-vessel, and means lfor rotatingthe actuatingshaft, substantially as described.

2.
